How this service works
Is the domain's DNS hosted by vultr? Looks up the NS records (Cloudflare DoH) and matches them against vultr's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.
Output
Returns a yes/no indicator of whether the domain's DNS is hosted by Vultr, the full list of NS records resolved via Cloudflare DoH, and specifically which nameservers matched Vultr's known patterns.
Example use cases
Sales prospecting for Vultr customers
“I'm doing outreach to companies that use Vultr infrastructure — can you check if stripe.com is running its DNS through Vultr so I know whether to pitch our Vultr-focused migration tool?”
Security audit of competitor infrastructure
“I'm mapping out which of our competitors are using Vultr for DNS — can you check whether shopify.com is DNS-hosted by Vultr and show me which nameservers matched?”
Pre-migration DNS vendor check
“Before we start the migration plan, I need to confirm whether acme.com is currently using Vultr for DNS hosting — can you look up their NS records and tell me if any match Vultr's nameserver patterns?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/vultr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to definitively determine whether a specific domain's DNS infrastructure is managed by Vultr, particularly for sales prospecting (identifying Vultr customers), security audits (mapping Vultr-hosted assets), or pre-migration vendor assessment. Prefer this over generic NS lookup endpoints when you want structured Vultr-specific pattern matching and a clear yes/no answer rather than raw DNS data.
Side effects
- Domain does not exist or has no NS records — returns empty result or error
- Domain uses non-Vultr nameservers — returns no match with the NS records listed
- Cloudflare DoH is temporarily unavailable — lookup fails with a network error
- Malformed or invalid domain name input — request rejected or returns error
- Timeout if Cloudflare DoH response is slow
